Oh this is funny. When I was in Toronto working my company issued me an F-150. It was a 1998 w/ 4.2 V6, Auto.
I was out at a customers site with one of my salesmas. He had a 2000 4.6 w/auto. On the way back we set up a little race. It was from a light up a slight hill. Both trucks were empty (although he had slightly oversized tires).
I won in the V6!
It was so funny. I'd never expect the V6 to take the V8. I think it also had something to with his tires. They were between 1" and 2" in diameter larger.
Right after that they guy was a little pissed so he asked me what he could do to get more power real cheap (and with out actually changing the truck as it was a company truck too). I got him to put a K&N in and I left before we could race again.
I'd be curious to see the out come.
Both trucks were 2WD.
